CHESTER, Pa. — Roger Torres scored within a minute of coming on as a second-half substitute and gave the Philadelphia Union a 1-0 win over the Red Bulls last night.

Torres entered the match in the 67th minute and then found himself in perfect position less than a minute later. Red Bulls defender Tim Ream passed the ball directly to Philadelphia forward Danny Mwanga, who then took a couple of dribbles and left Torres an easy ball to send into the net.

The Red Bulls fell to 1-1-2. They allowed just their second goal of the season, and four combined goals have been scored in their four matches.

Rafael Marquez, Roy Miller and Dane Richards — who was replaced by forward Luke Rodgers in the 68th minute as the Red Bulls searched for an equalizer — were assessed yellow cards.

Union goalkeeper Faryd Mondragon earned his third victory and third shutout this season. Philadelphia already has more shutouts than in all of last season.

The Union (3-1-0) moved into first place in the Eastern Conference with nine points.
